Abstract (en)
[origin: US2021219924A1] An integrated bioinstrumentation system, combining an accurate and robust quasi 1D computational model with experimental peripheral measurements, is designed to extract information on other quantities of interest, for which the direct measurements are not feasible. The system is able to quantify and visualize the distributions of a cardiac output (CO), aortic blood pressure (BP), flow, velocity, and aortic arterial compliance, based on a peripheral analysis of a pulse transit time (PTT) measured at the available peripheral sites. A preliminary calibration stage extracts the arterial properties from simultaneous measurements of a pulse transit time, and an upper arm blood pressure. Obtained transfer functions, linking noninvasive peripheral measurements to the aortic pressure, cardiac output, aortic compliance and others serve to quantify the indicators of cardiac morbidity and mortality.
